Data profiling is the process of examining the data available in existing data sources (e.g. databases, applications, files, etc.) and collecting statistics and information about this data. Data profiling enables the assessment of the quality level of the data contained in the information system, according to a defined set of metrics and goals. Talend Open Profiler allows business users or data management staff to define a set of indicators for each data element that needs to be analyzed or monitored. It produces sophisticated reports and graphs that let users gauge at a glance the level of quality of the data and the status of the indicators that were defined.
